Installation
1.
Disconnect power to the keypads by turning off all
circuit breakers connected to the HomeWorks
Interactive Processor or keypad link auxiliary
TM
power supply.
Wiring with power ON may result in
personal injury.
2.
Address keypads. Assign a unique address to
each keypad using the DIP switch settings. See
Figure 1 for DIP switch location, and Figure 4 for
DIP switch settings. Be sure to record the address
for future programming purposes.
3.
Strip insulation or trim keypad link wires to 3/8"
(10mm). Each terminal will accept one or two
No. 18-gauge (1.0mm 2
4.
Unplug the keypad link terminal block from the
keypad.
5.
Connect wiring to terminal block as shown in
Figures 2 and 3.
6.
Plug the keypad link terminal block back onto the
keypad.
7.
Connect to External Input Closures (optional). All
seeTouch keypads accept two low-voltage dry
TM
contact closures. Connect wiring for closures to
control if required. See Figure 2.
When using the external input closures:
Verify compatibility of input devices. The external
input closures are intended for use with devices
that provide dry contact closure outputs. The
external input closures can be used with ground-
referenced, solid-state outputs if the outputs have
an on-state saturation voltage of less than 2 VDC
and an off-state leakage of less than 50 µA. Dry
contact or solid-state outputs must be capable of
switching 15 VDC at 10 mA. The outputs must stay
in the closed or open states for at least 40 msec in
order to be recognized by the keypad. If there is
any question as to whether the device is
compatible with these specifications, contact the
manufacturer.
8.
Mount keypad as shown in Figure 5. Do not over-
tighten mounting screws.
9.
Install seeTouch faceplate kit (SK-xxxx-xx-xx-x).
